## Summary
- Bumps `twenty-sdk` / `twenty-client-sdk` to the exact `2.19.0-alpha.1`
prerelease for the apps under `packages/twenty-apps` that actually
target a mutated standard identifier, and refreshes their lockfiles.
- Declares `"engines": { "twenty": ">=2.19.0" }` in those apps so
pre-2.19 servers refuse to install or upgrade to the rebuilt packages.
Only apps that reference a standard object's **system-field** universal
identifier, define a **relation into** a standard object, or call the
field-UID derivation helper need 2.19 (the identifiers those touch
changed from hardcoded UUIDs to deterministic hashes). Apps that only
define their own custom objects, or add plain scalar fields to a
standard object via its stable object-level id, were left on their prior
SDK pins. Currently bumped: `postcard`, `self-hosting`,
`twenty-partners`, `call-recorder`, `people-data-labs`,
`twenty-last-contact`.
## Context
Follow-up to #22565 (deterministic system field universal identifiers)
and #22599 (SDK prerelease bump).
Packages built with SDK ≤ 2.18 carry legacy system field identifiers and
are rejected by servers running `main`. Rebuilding with the 2.19 SDK
fixes that — but a rebuilt package must not be *upgraded into* by a 2.18
server, since 2.18 has no deterministic-identifier validation and would
diff the changed system field identifiers as a destructive delete +
create (the 2.19 backfill has not run there yet).
The `engines.twenty` constraint closes that gap: `doInstallApplication`
validates it via `validateServerCompatibility` before any mutation, and
this check has shipped since ~2.10, so every 2.18 server enforces it.
Resulting matrix:
- 2.18 fresh install of a rebuilt app: works, converges as a no-op once
the 2.19 backfill runs
- 2.18 upgrade of an existing install: rejected with
`SERVER_VERSION_INCOMPATIBLE` before any mutation
- 2.19 (post-backfill) install/upgrade: syncs cleanly
## Expected CI failures
**The `CI Twenty Apps` integration-test jobs are expected to fail on
this PR** (e.g. `people-data-labs`, `twenty-partners`). This is a
server-version mismatch, not an app bug — lint, typecheck and unit tests
all pass:
- The integration step spawns a real Twenty server from Docker Hub
`twentycrm/twenty-app-dev:latest` and runs `twenty dev` to sync each
app's metadata into it.
- `latest` currently resolves to **v2.18.5** — no `2.19` image is
published to Docker Hub yet.
- These apps now reference 2.19's **deterministic system-field universal
identifiers** (e.g. `company.createdBy`, `opportunity.createdAt`). A
2.18 server still carries the legacy identifiers, so the sync rejects
every 2.19-derived reference with `INVALID_VIEW_DATA` /
`FIELD_METADATA_NOT_FOUND` ("Field metadata not found").
- The failure surfaces as low-level field errors rather than a clean
`SERVER_VERSION_INCOMPATIBLE` because the `engines.twenty` gate
(`validateServerCompatibility`) only runs on the `app:install` / publish
paths — **not** on the `twenty dev` dev-sync path the integration tests
use.
These jobs will go green automatically once `twenty-app-dev:2.19` is
published to Docker Hub (or once CI pins the spawn action's
`twenty-version` to a 2.19 tag).
## Intentionally not included
- App `version` fields are untouched; they'll be bumped at publish time.
## Test plan
- [x] Refresh each bumped app's `yarn.lock` (`2.19.0-alpha.1` is now on
npm)
- [ ] Rebuild one app manifest and verify default field identifiers
match `getFieldUniversalIdentifier`
- [ ] Verify a 2.18 server rejects an upgrade to a rebuilt package with
`SERVER_VERSION_INCOMPATIBLE`
- [ ] Re-run `CI Twenty Apps` integration jobs once a
`twenty-app-dev:2.19` image is available

Self Hosting
The Self Hosting app collects sign-up telemetry from self-hosted Twenty instances and turns it into structured CRM records. Each time a user signs up on a self-hosted instance, the app records who they are, which instance they belong to, and automatically links them to a matching Person in your workspace.
What it does
- Receives sign-up events from self-hosted instances through a public telemetry webhook.
- Creates or updates a Self Hosting User record for each real sign-up, keyed by email address.
- Automatically matches every Self Hosting User to an existing Person by email, creating a new Person when none is found, and keeps that link up to date as the data changes.
- Filters out test and example sign-ups so they never enter your CRM.
- Carries a rich set of person and company enrichment fields so each sign-up can be augmented with firmographic data.
What it adds to your workspace
Self Hosting User object
A new object, Self Hosting Users, stores one record per self-hosted sign-up. Its fields include:
- Identity: Name, Email, Domain, Locale. The webhook only populates Name, Email, and Locale; Domain exists on the object but is not filled in by the sign-up flow.
- Instance: Server URL, Server ID, User ID, User Workspace ID.
- Relations: Person, the matched standard Person record for this user.
- Aggregate: Number of Emails with Same Domain, a count of users sharing the same business domain. This field is part of the data model but is not populated by the app's own ingestion or matching logic.
- Enrichment state: Is Enriched, Tried To Be Enriched, Is Personal Email, Is Twenty.
- Person enrichment: City, Country, Job Function, Job Title, LinkedIn, Seniority.
- Company enrichment: Name, Description, Industry, Industries, Employees, Founded Year, Annual Revenue, Funding Latest Stage, Funding Total Amount, Alexa Rank, LinkedIn, Tags, Tech.
Person relation
The standard Person object gains a Self hosting users relation, so you can see every self-hosted sign-up tied to a given person directly from their record.
View and navigation
A Self hosting users table view exposes all of the fields above as columns and is added to the left sidebar for quick access.
Role
The app ships a default role with read, update, and soft-delete permissions over workspace records. Permanent deletion is not granted.
How sign-up data flows in
The app exposes an unauthenticated HTTP endpoint that self-hosted instances post telemetry to:
- Method:
POST - Path:
/webhook/telemetry
A request is processed only when its action is user_signup; any other event type is acknowledged and ignored. The payload carries the user's email, first and last name, locale, the originating server URL and server ID, and workspace identifiers.
When a valid sign-up arrives:
- Non-signup events are acknowledged and ignored first; then sign-ups with no email are skipped; then sign-ups whose email contains
testorexample(case-insensitive) are ignored. - If a Self Hosting User already exists for that email, it is updated with the latest details; otherwise a new one is created. The app persists Name, Email, Locale, Server URL, Server ID, User ID, and User Workspace ID; Domain and the enrichment fields are left for separate processes.
- Whenever a Self Hosting User is created or its email changes, the app looks for a Person with the same email. If one exists it links them; if not, it creates a Person and links it. Records that already have a matched Person and an unchanged email are left untouched.
Configuration
This app requires no server or application variables. To send data into it, point a self-hosted Twenty instance's telemetry at the webhook path above on the workspace where this app is installed.
Limitations
- The telemetry webhook is intentionally unauthenticated and performs no signature or shared-secret verification. Any client that can reach the endpoint can submit sign-up events, so it should only be exposed to trusted self-hosted instances.
- Test/example filtering is a simple substring match: any email containing
testorexampleanywhere is excluded, even if it is a legitimate address. - The enrichment fields and the Domain field are part of the data model but are populated by separate processes; the app itself ingests sign-ups and performs Person matching.
